To all yw'zom t may concern.'

Be it known that l, ALFONSO M. LnoNI, a citizen oi' the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful improvements in liront-Axle Constructions, of which the following is a specification.

rlhis invention relates to a three-point suspension for motor trucks or vehicles, wherein an extremely simple type of mounting is provided between the vehicle frame and the front axle, the movable parts volf which are well protected while yet readily accessible.

rlhe improved suspension mounting involves a cross-trame having removable rigid connection with the longitudinal main frame bars of the vehicle, which frame has depending plate portions to extend beyond and on opposite sides of a housing recess formed in the liront axle. A pedestal base is pivotally supported in said housing recesson a trans' verse pin, and the ends of the base, in both directions beyond the pivot pin, have a yielding connection with the cross-frame through spring pressed bolts.

ln the drawings z*- u Fig. 1 is a broken view in front elevation, illustrating the improved suspension mounting.

Fig. 2 is a section on line 2 2 of Fig. 1.

The improved suspension mounting com? prises a cross-frame 1, having a central or body portion 2, lateral wing portions 3, and

depending plates 4t, all preferably constructed as an integral formation. The wing portions 3 have channeled bearing ends '5, whereby the cross-frame may be bolted or otherwise rigidly secured in a removable mannerA to the longitudinal frame bars 6 oli' the vehicle frame.

The front axle 7 of the vehicle is centrally formed with a housing recess 8, of appropriate size, the axle being reinforced or otherwise strengthened to avoid weakness at the recessed portion. A. pedestal base 9 is mounted within the recess 8, on a pivot-pin 10, extending transversely of the recess and through the walls thereof. The base 9 is straight on the upper face, with a centralv depending portion 11 to' receive the pivotpin, and the lateral arms 12 of the base thus provided, are formed with openings to receive the lower ends of bolts 13, which eX- tend upwardly and through vthe cross-frame. The bolts are fixed in the pedestal arms 12, and extend loosely through openings formed in overlyingpartsy or partitions of the cross-frame body, with the upper termi,

nals'oi the bolts provided with means, as nuts 14 to prevent complete separation of the connection, while permitting the necessary compensating movement.

The bolts 13, within the body of the crossrame, are diametrically reduced, as at 15,` and coil springs 16 encircle the reduced por` tions, bearing between the shoulder `formed by the reduction of the bolt, or an enlargement thereon, and an abutment 17 formed yor provided in the body. i l f rEhe plates 4 depend from the bodyof the crossrame on opposite sides of and nor' mally below the front axle 7., These plates gradually converge toward their lower ends andare formed at appropriate points with elongated openings 18, to permit passage therethrough of the projecting ends'ot` thev pivot-pin 10, and thereby removal offsuch The plates 4 serve to guide the parts in sopy play under load strain, and to take care as a covering of moving parts.

The suspension action is apparent from the drawings; it being obvious that any sur- .tace conditions tending to a deliection of the front aXle is distributed through the pedes I tal base andA taken up bythe springs 16 through movement of the bolts in the action of the pedestal base.

The cross-frame, asV shown at 19, may and preferably is formed to receive the engine frame supports, so.y that such cross-frame may also serve as the sole support for the forward end of the engine. l

Having thus described the inventiomwha is claimed as new, is v 1. Amo-torvehicle frame suspension, com-- prising a cross-frame secured to the vehicle trausereey of the recesss a pedesal base mounted on said pin Within the recess, a

lfoss-imm@ secured to the Vehicle ame, and spying-loaded bols Connected to said base and movable Within the cxoss-ame, seid Cross-iframe having plates depending on both Sides of the axle and formed with openings in alignment with the pvot pin.

1n testimony whereof I aIX my signature.
